Be it known that I, HENRY G. MILLS, a citizen of the United States, residing at Mil. waukee, county of Milwaukee, and Sta-te W'isconsin, have invented certain new and useful Improvements in Fountain-Pens, of which the following is aspecification.

My invention relates to fountain pens and. the object of my invention is to provide a self iilling fountain'pen of improved construction.

A lfurther object of m invention is to provide a selffilling fountain penwhich may be readily and easily operated, of low'cost to manufacture and one which shall Apresent a neat appearanc'e,`

lOther objects will appear hereinafter.

My invention will be more readily understood by reference to lthe accompanying drawings forming apart of this specification and in which,l y

The upper end of the barrel is 4 formed integrally therewith and of reduced diameter.- The nipple, 4 isboth externally and 6 for purposes hereinafter described. -7 indicates a conipressib bulb, by means of which the reservoir, 2 -is filled. The bulb 7 is of substantially the same diameterI as the ni iple, 5 or slightly long to give it suflicient capacity.

As the bulb expands it draws the ink into the reservoir, 2 after which the shield 10 is re-- placed. To prevent the ink from entering thebulb when in upright position, when in the pocket, the bore, 12' of the lug, S is made quite small.
